When the wire is fed along the required distance to provide the necessary length for the staple blank and the movable cutter again descends, another blank is severed, and so on. In this way, there is formed a staple blank27 havingsubstanfrom rising with the movable cutter 19 when.

- it ascends after the cutting operation. Thus it will be seen that by the action of the point bending device 33, when the staple blank is completed both points lie substantially in a plane coinciding with one side of the staple blank, it being understood that the wire employed is substantially rectangular in cross.

I have chosen to Illustrate my invention in connection with a machlne of the class of which the machine of the patent to Cummings et al., No. 493,910, dated March 21, 1893, is an example. I will now proceed to describe the mechanism by which the staple blanks are bent to form the staples and the staples are driven into the work, this mechanism being substantially thesame as the mechanism for such purposes employed in connection with the patent to which I have just referred.

36 is a staple former and carrier which is carried by a floating lever 37 which is carried forwardly and rearwardly at the proper times in the operation of the machine by a link 38 connecting said lever to a cam lever 39 having journaled thereon a cam roll 40 located in a cam groove 41 formed in a cam 42 secured to a driving shaft 43 which is journaled in suitable bearings in the frame 44. A wire clamp 45 pivoted at 46 to the staple carrier and former 36 is provided at its front end with a notch 47 adapted to receive the wire, the front end of said clamp being pressed downwardly toward said carrier by means of a suitable spring 48. The staplecarrierjand former 36 is provided in itp uppepsideivith a bevel face 49' and the clamp 45' is provided -near its lower side wvith a bevel face 50, which bevel faces converge toward each other toward the righthand side of the machine.- When the wire is fed through the wire guide 18 and across the top of -.he stationary cutter 15, said wire passes be ween the upper side of the staple carrier and former 36 and the lower side of the clamp 45, the bevel faces 49 and 50 insuring the proper passage of the advancing end of'the wire be, tween the carrier 36 and clamp 45. After the wire has been fed the proper distance,

the carrier 36 and clamp 45 move rear--.

wardly,until the wire passes into the notch 47 so that when the wire is severed, as

hereinbefore described, the severed portion which constitutes the blank from which the staple is to be formed is held by said carrier and clamped at a pointmidway be-' A vertical or reciprocatory movement is I impartedto the slide 52 by means of a link 54 pivotally connected at its lower end to said slide and at its upper end to a bell crank lever 55 having-journaled thereon a cam roll 56 located in a cam groove 57 formedin a cam 58 secured to the driving shaft 43. The throat 51 is provided with a groove 59 in which a driver 60 is arranged to reciprocate, said driver being secured to a driver slide 61 to which a vertical reciprocatory motion is imparted by means of a link 62 pivoted at its lower end to said slide,

and at its upper end to a bell crank-lever 63 having journaled thereon a cam roll 64 located in a cam groove 65 of a cam 66 secured to the driving shaft 43. The blank being held by the clamp 45, asshown' in.-

Fig. 3, the throat 51 descends from the position shown in Fig. 3 to the position shown in Fig. 5, during which time the two sides of said throat act to bend thefree ends of said blank downwardly to form a staple, as shown in Fig. 5, the legs of said staple being held by frictional contact with the opposite sides of the groove 59. The staple carrier and former 36 and-the clamp 45 then retreat or, in other words, move toward the left from the position shown in I Fig. 4, thus leaving the staple held by fric- .tional engagement with the opposite sides of the groove 59. T

Atthe proper time in' 'tlie operation of the machine, the throat 51 descends carrying the points of the staple into contact with or closely adjacent to the material into which the same is driven, afterwhich-the driver 60 descends and drivcs'the staple through the material, as shown in Fig. 6,

the points of the ,staple being clenched against a horn 67. -When the po nts of the prongs or legs of the staple strike the upper end'of the born 67, said points, owing to the v fact that they conver e toward each other, turn inwardly towar each other, as illus- 13, nwin? k) the fad; flux;
